Mark parked his car at the carpark from 2.57 p.m to 8 p.m. How much did he pay for his parking?
From 2.57 p.m. to 3.57 p.m.: 1 h
From 3.57 p.m. to 8 p.m.: 4 h 3 min
1 h = 60 min
4 h 3 min = 4 x 60 + 3 = 243 min
Number of sets of addtional 30 min in 5 h 3 min
= 243 ÷ 30
= 8 r 3
Number of sets of 30 min that Mark had to pay for
= 8 + 1
= 9
Amount that Mark had to pay for 9 sets of additional 30 min
= 9 x 1.50
= $13.50
Total amount that Mark had to pay for his parking
= 2.30 + 13.50
= $15.80
Answer(s): $15.80
